Dear Ahmet, This will almost surely give you nonsense, since it produces a fitted probability ignoring the constant in the model (assuming that there is one), setting other predictors to 0 and the predictor in question to 1. What is it that you want to do? I hope that this helps, John ----------------------------------------------------- John Fox Department of Sociology McMaster University Hamilton, Ontario, Canada L8S 4M4 email: jfox at mcmaster.ca phone: 905-525-9140x23604 web: www.socsci.mcmaster.ca/jfox -----------------------------------------------------
thank you
Say, I just want to find each predictor's particular effect on dependent
variables.
Actual model is to prepare landslide susceptibility map on GIS. So I
want to know
what the effect as probability value comes from each predictor. For
instane what is the effect
of slope on landslide susceptibility. Should I keep others constant ?
kind regards
